Wind power generation power supply is composed of wind power generation units, towers that support generators, battery charging controllers, inverters, loaders, grid -connected controllers, battery packs, etc.; It contains composition of leaves, wheels, replenishware, etc. It has functions such as turning power and turning the head of the generator by the blades. Wind speed selection: Low -air speed wind turbines can effectively improve the use of wind energy use of wind turbines in low air speed areas. In areas where the average annual wind speed is less than 3.5m/s, and there is no typhoon, low wind speed products are recommended.
When the wind power generation crew is generated, the output frequency must be guaranteed to be constant. This is very necessary for both fan grid -connected power generation or complementary power generation power generation. To ensure that the frequency of wind power is constant, one way is to ensure the constant speed of the generator, that is, the constant -speed constant frequency operation method, because the generator is driven by the wind machine through the transmission device, so this method will undoubted Speed speed, this method will affect the conversion efficiency of wind energy; another method is to change the speed of the generator speed with the wind speed. It ensures that the frequency of the output power is constant through other means, that is, the transmission constant frequency operation. The wind energy of the wind machine is related to the leaf tip speed ratio (the line speed of the leaf tip and the ratio of the wind speed), and there is a certain determined leaf tip speed ratio to maximize the CP. Therefore, under the speed frequency operating mode of the gear shift, the speed of the wind machine and the generator can change to a large range without affecting the frequency of output power. Therefore, the wind power generation unit often uses the gear frequency frequency method to ensure that the output frequency is constant
